      x86: Add "make tinyconfig" to configure the tiniest possible kernel · 0da1d4a0
      由 Josh Triplett 提交于 
      Since commit 5d2acfc7 ("kconfig: make
allnoconfig disable options behind EMBEDDED and EXPERT") in 3.15-rc1,
"make allnoconfig" disables every possible config option.

However, a few configuration options (CC_OPTIMIZE_FOR_SIZE,
OPTIMIZE_INLINING) produce a smaller kernel when turned on, and a few
choices exist (compression, highmem, allocator) for which a non-default
option produces a smaller kernel.

Add a "tinyconfig" option, which starts from allnoconfig and then sets
these options to configure the tiniest possible kernel.  This provides a
better baseline for embedded systems or efforts to reduce kernel size.

      x86, platform, kconfig: move kvmconfig functionality to a helper · 3aaefce1
      由 Josh Triplett 提交于 
      The new mergeconfig helper makes it easier to add other partial
configurations similar to kvmconfig.  Architecture-independent portions
of those partial configurations should go in
kernel/configs/${name}.config, and architecture-dependent portions
should go in arch/${arch}/configs/${name}.config.

Based on a patch by Luis R. Rodriguez <mcgrof@suse.com>.
Originally-Signed-off-by: NLuis R. Rodriguez <mcgrof@suse.com>

Modified to make the helper name more general than just virtualization,
support architecture-dependent and architecture-independent partial
configurations, move the helper and kvmconfig to
scripts/kconfig/Makefile, and factor out more of the common file path.

      kconfig: Document oldnoconfig to what it really does · 67d34a6a
      由 Steven Rostedt 提交于 
      The make target 'oldnoconfig' is a misnomer. It doesn't set new symbols
to 'n', but instead sets it to their default values.

Unfortunately, assuming that it actually did this, broke ktest in some
of its tests. For example, the tests to create a minimum config and even
a config bisect, depends on removing various configs and using
oldnoconfig to get rid of other configs that may have depended on it.

But because some configs that it was trying to disable, were in fact
default enabled, this caused those configs to re-enable and corrupt the
test.

I thought about fixing oldnoconfig, but I'm afraid that people are
already dependent on its current behavior. Instead, I'm just updating
the documentation to state that it sets the new symbols to their default
values and not to 'n'.

Ideally, this would be called, 'olddefconfig' and we have an
'oldnoconfig' that actually disables the new symbols. But it's useless
for me now. If it changed, ktest would need to be consistent between
each version, and that would be to difficult to detect. I'll handle this
issue with ktest with other means.
